In my opinion, I think is a good idea to have a mentor to teach you more about trading an guide you hope. Searching about trading and trying to learn on Internet, I don't think you can learn everything in the Internet because not everything they will teach you about trading. But if you have mentor that you know and believe that won't run with your funds, and is honest enough with you am sure you will get better understanding then Internet. Leaning through physical explanation is more good then just looking at the smartphone on YouTube trying to learn. Trading is risky and I can says is no for anyone, because is very risky and know one can bear the risks involved. Because they have many traders that have stop trading because of the loses, so they stop and go back to investment.
Not sure, mentors are all different and not all of them are the same. So when you are talking about something, the difference is huge. You need to realize this isn't one of those situations where it's one paint brush all over them. Yes there are people who could be a great mentor to some newbie and he would do a great job, but that doesn't mean that all mentors are great.
Because sometimes there could be some mentor who will teach a horrible job and that would not be easy at all. This is why I believe we can't really make a lot of money based on any of this, and that can't be considered a good thing. So yeah, mentorship is fine, but that doesn't mean all mentors are good, if you can find a good mentor, then you can do a good job.
